During idle use with LVDS on (brightness as low as possible), my laptop uses between 8,3W and 8.8W.
During idle with lvds turned off (DPMS off), it uses 8,4W.
Measured with powertop.

This means I have no real powersaving, by letting it turn off the monitor !

Normally I could win ½ hour on batter by letting dpms turn off the lvds.

Please look into this.
